CodePen

We’ve made several upgrades to uploading/hosting images on CodePen lately. One change, moving to the open-source file-uploading library Uppy, was driven by business concerns. But the benefits are good for everyone: uploads are faster, and the money we saved let us increase file size limits and total... read more

Stephen and Chris jump on the podcast to talk about our (ahem, super cool) deployment feature. Any Pen can be a website! Well, they kinda are already, but you know what I mean. If you’re a PRO user all you do is click a button and the Pen is instantly deployed at a *.codepen.app website. […]... read more

Choosing beautiful and unusual fonts and implementing them in visually compelling ways is certainly a way to stand out in this period of so many websites looking same-y. I figure it’s a good week to send some sweet typography links I’ve saved (in the form of screenshots): Notable to me: Apple has a ... read more

Dave Rupert has a new syntax highlighter: MicroLighter. He wrote about the why. There are a bunch of trade-offs with all the technologies that do this job. The trade-offs here seem pretty worth it for a relatively lightweight, infrequent syntax highlighting job. I mean 2 KB as a base library is pret... read more

Marie and Chris talk about CodePen Challenges. We’ve been at it for many years!

Time Jumps... read more

Rach and Chris jump on the podcast to talk about the brand-new in-app notification system we built and shipped. We’re actively trying to balance a system that isn’t annoying, but allows us to show targetting information to targetted users when we think that’s valuable for both you and us. It started... read more

Very cool that random() in CSS is coming to Chrome to join Safari who led that feature. It means one of my favorite demos I’ve made when I was first playing with it will work for more people. I just like how little code it is and how it combines some fun modern CSS features. […]... read more

Normal text wrapping can leave big gaps in your container, which can become even more exaggerated with the new-ish CSS values of text-wrap: balance and text-wrap: pretty. You almost certainly want to use balance or pretty because they do a great job preventing “dangling” lines in your text, even wit... read more

Stephen just implemented a great UI feature for the 2.0 editor where all the Panels that were previously stuck to the left side of the page can now be dragged away to become an “Editor Tab” just like a file (or Block!). Now you’ve got a lot more freedom for what you’re looking at, and […]... read more

I got a cool trick for you. You can just paste an HTML email into Gmail. So let’s say you’re using (the very nice) MJML language to create an nice responsive cross-client-compatible email on CodePen. Like this one. You can just select all that nice visual output and Copy it. Then in Gmail, make a […... read more
